- The nature of my invention consists in the construction andarrangement of a sod and dirt scraper, as will be hereinafter more fullyset forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure 1 is a side view, Fig.2 is a front View, and Fig. 3 a plan Viewof my. machine.

A A represent a series of bars, arranged horizontally and having theirrear ends curved downward, forming each a hook or strong tooth, B.Instead of bending or curving the bars A A their hooks or teeth may bemade separately, and bolted or riveted to the bars. The bars A A are, infront of the point where they commence to bend, rigidly attached to abeam, 0, which may be made of wood or iron. The bars may be attached tothis beam in any suitable manner to keep them in their proper places. Dis a thin plate of iron or other metal attached by means of staples a ain the curve to theteeth B B. This plate answers the double purpose ofstrengthening the teeth, and to carry the loose dirt along with thesods. E is a frontbeam, running parallel with the rear beam G, andrigidly connected with or attached to the bars A A. The beam E may bemade of wood or metal, and is provided with a staple, b, and hooks d (lfor attaching either one or two horses to draw the scraper over theground.

G G are handlesfor guiding the scraper, which may be attached either tothe rear beam (J or to the two outside bars A, and they are connected bya rod, I.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The scraper shown and described, when provided with the metal plate D,attached by means of the staples a a to the hooks or teeth B B, allsubstantially as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this24th day of August, 1871.
